3 BACKGROUND
[0003] 3.1 Field of the Invention
[0004] This invention relates to wireless telecommunication. In
particular, the various embodiments of the invention relate to
monitoring and tracking wireless communications devices and their
activities, the construction and management of applications for
performing such functions, the monitoring of activities and data
stored in mobile devices, and the transparent exfiltration of
collected information from monitored mobile devices using wireless
links. The present invention has applications in fields of computer
science, electronics, telecommunications, and security.
[0005] 3.2 The Related Art
[0006] Mobile devices include pagers, mobile phones, and
combination devices that include the functionality of mobile
phones, pagers, and personal digital assistants (PDAs). These
devices allow the exchange of textual information (e.g., using
pagers, cell phones, or PDAs) as well as voice and data (e.g.,
using cell phones and PDAs). Mobile devices have also recently been
integrated with useful features such as global positioning system
(GPS) access, cameras, and scanners (including scanners able to
process radio frequency identification (RFID) and barcodes), and
magnetic data storage cards. Wireless communication ("wireless")
allows two or more electronic devices to exchange information
without the need for a physical connection (i.e., a wire or cable)
between the devices, using radio or microwave transmissions; and
devices using wireless communications can be fixed or mobile.
Unlike traditional "wired" technologies, wireless communication
technologies permit users to operate from any location at which
there is sufficient wireless signal power to enable the
communication. Fixed wireless devices allow wireless communication
from a fixed location to mobile device. Mobile wireless permits
communication between several mobile devices; and mobile devices
generally communicate using radio-frequency transmissions.
[0007] Transmitters send a signal from a wireless communication
point-of-presence to a mobile device, while receivers process a
signal received at a point-of-presence from a device. A
point-of-presence is a collection of one or more transmitters and
receivers that can communicate with a mobile device. For example, a
fixed point-of-presence can be a communication tower in a cellular
telephone network or a wireless local area network connection at a
coffee shop. Fixed points-of-presence are typically spaced so that
their ranges overlap to allow continuous communication as a device
moves amongst various locations. A mobile point-of-presence can be
any other mobile device that is not a fixed point of presence. An
example of a mobile point of presence is a laptop accepting WiFi
connections or a mobile telephone handset accepting WiFi or
Bluetooth. As long as a connection can be made between the
point-of-presence and the mobile device, information can be sent
and received appropriate to the capabilities of the device. But in
many environments, such constant contact between a mobile device
and a point-of-presence is not possible; because areas exist which
are not in range of a point-of-presence, and variances of land or
building materials may interfere with the signal. As a result, a
mobile device can be out of coverage for a few minutes or hours,
and mobile phone calls, wireless internet connections, and access
to mobile points of presence may be cut off unexpectedly.
[0008] More recently, mobile devices have allowed application
programs to be written to manage data communication (and not just
voice) to and from the device so that more advanced functionality
can be enabled in the device without connecting the mobile device
to a computer or other device to download and install the
application programs. Such applications can communicate with other
devices, such as networked computers and other electronic equipment
(including other mobile devices). Examples include the ability to
send and receive email; review and process calendar, tasks,
contacts, and other personal information manager records; retrieve,
display and manage stock data; find and display nearby restaurants
or clothing stores; and to receive or send documents and files
using a mobile device. Alternatively, these applications rely upon
an always-available Internet connection, and communicate using
standard Internet techniques and protocols (for example, sockets,
UDP (User Datagram Protocol), TCP (Transmission Control Protocol),
and HTTP (HyperText Transfer Protocol)). In some cases,
applications make use of WAP protocols and associated WAP Gateways
to access Internet resources when the device's display resolution
or other capabilities are inadequate for full Internet access.
Wireless Application Protocol (WAP) is a standard implemented
through WAP Gateways which are servers that act as communications
bridges between wireless devices and internet services,
transferring data between devices and services, and transforming
data as required between the various protocols used. Each of these
methods relies on the wireless connection being available when
needed.
[0009] A user's employment of a mobile device, and the data stored
within a mobile device, is often of interest to individuals and
entities that desire to monitor and/or record the activities of a
user or a mobile device. Some examples of such individuals and
entities include law enforcement, corporate compliance officers,
and security-related organizations. As more and more users use
wireless and mobile devices, the need to monitor the usage of these
devices grows as well. Monitoring a mobile device includes the
collection of performance metrics, recording of keystrokes, data,
files, and communications (e.g. voice, SMS (Short Message Service),
network), collectively called herein "monitoring results", in which
the mobile device participates. Network management applications
monitor device performance in order to identify network and device
performance issues. Additional applications of monitoring
technologies include the protection of corporate information and
ensuring information covered by non-disclosure agreements is not
inappropriately distributed. For example, recent high profile
securities fraud cases have identified users who have sent details
of upcoming mergers and acquisitions to accomplices who use the
information for personal profit. Similarly, monitoring technologies
provide advantages to law enforcement as the criminal element
increasingly uses portable mobile devices to communicate and manage
their criminal enterprises.
[0010] Mobile device monitoring can be performed using "over the
air" (OTA) at the service provider, either stand-alone or by using
a software agent in conjunction with network hardware such a
telephone switch. Alternatively, mobile devices can be monitored by
using a stand-alone agent on the device that communicates with
external servers and applications. In some cases, mobile device
monitoring can be performed with the full knowledge and cooperation
of one of a plurality of mobile device users, the mobile device
owner, and the wireless service provider. In other cases, the
mobile device user or service provider may not be aware of the
monitoring. In these cases, a monitoring application or software
agent that monitors a mobile device can be manually installed on a
mobile device to collect information about the operation of the
mobile device and make said information available for later use. In
some cases, this information is stored on the mobile device until
it is manually accessed and retrieved. In other cases, the
monitoring application delivers the information to a server or
network device. In these cases, the installation, information
collection, and retrieval of collected information are not
performed covertly (i.e. without the knowledge of the party or
parties with respect to whom the monitoring, data collection, or
control, or any combination thereof, is desired, such as, but not
limited to, the device user, the device owner, or the service
provider). The use of "signing certificates" to authenticate
software prior to installation can make covert installation of
monitoring applications problematic. When software is not signed by
a trusted authority, the software may not be installed, or the
device user may be prompted for permission to install the software.
In either case, the monitoring application is not installed
covertly as required. Additionally, inspection of the mobile device
can detect such a monitoring application and the monitoring
application may be disabled by the device user. Alternatively, OTA
message traffic may be captured using network hardware such as the
telephone switch provided by a service provider. This requires
explicit cooperation by the service provider, and provides covert
monitoring that is limited to message information passed over the
air. As a result, service provider-based monitoring schemes require
expensive monitoring equipment, cooperation from the service
provider, and are limited as to the types of information they can
monitor.
[0011] Additional challenges are present when the monitoring
results are transmitted from a mobile device. First, many mobile
devices are not configured to transmit and receive large amounts of
information. In some instances, this is because the mobile device
user has not subscribed to an appropriate data service from an
information provider. In other instances, the mobile device has
limited capabilities. Second, transmitting information often
provides indications of mobile device activity (e.g. in the form of
activity lights, battery usage, performance degradation). Third,
transmitting information wirelessly requires operation in areas of
intermittent signal, with automated restart and retransmission of
monitoring results if and when a signal becomes available. Fourth,
many mobile devices are "pay as you go" or have detailed billing
enabled at the service provider. The transmission of monitoring
results can quickly use all the credit available on a pre-paid
wireless plan, or result in detailed service records describing the
transmission on a wireless customer's billing statement. Lastly,
stored monitoring results can take up significant storage on a
mobile device and the stored materials and the use of this storage
can be observed by the device user.
[0012] Some devices have a removable identity card. SIMs are part
of a removable smart card, and the combination of a SIM and the
smart card is commonly referred to as a "SIM card". SIM cards
securely store the service-subscriber key used to identify a
subscriber to a given wireless network, and they also support the
SIM Application Toolkit (STK), which is a standard of the GSM
system that enables the SIM to initiate actions that can be used
for various value added services, such as payment authorization for
purchases. In GSM 2G networks, the STK is defined in the GSM 11.14
standard. In GSM 3G networks, the USIM Application Toolkit (USAT)
is the equivalent of STK, and is defined in standard 3GPP 31.111.
Both STK and USIM are referred to herein as "STK" when the context
does not require specification of the 2G or 3G versions
specifically.
[0013] The STK consists of a set of functions programmed into the
SIM card that define how the SIM can interact directly with the
device (commonly referred to in this context as a "handset"),
and/or the network. The STK provides functions that can give
commands to the handset, for example: to display a menu and ask for
user input, to dial phone numbers, or to control or access other
device features, such as GPS receivers and RFID readers. These
functions enable the SIM to carry out an interactive exchange
between a network application and the end user and to provide or
control access to the network. Details of STK capabilities and use
are defined in the 3rd Generation Partnership Project (3GPP)
Specification of the SIM Application Toolkit (STK) for the
Subscriber Identity Module-Mobile Equipment (SIM-ME) interface
(also known as the 11.14 specification) and related standards
documents.
[0014] In addition to the STK, SIM cards can implement additional
systems for supporting application programs that run on the SIM
card. There are a plurality of systems and standards for such
support, including the Open Platform and Java Card standards. Some
standards support only one operating system or hardware smart card,
others, like the Java Card standard, are supported on a plurality
of smart cards under a plurality of operating systems. These
systems can provide mechanisms for installing applications
programs, selecting applications to execute, and means for the
application programs to interact with each other or with the world
outside of the smart card they are running on. Thus, the open-ended
capabilities of applications installed on smart cards pose a
potential security hazard to the smart card and to devices in which
the cards are installed, similar to that of other general purpose
computing devices.
[0015] Although SIM cards originated with GSM devices, the cards
have proven so useful that other network types have adopted similar
mechanisms. For example, CDMA systems have implemented a SIM-like
device called a Removable User Identity Module (R-UIM), and a more
advanced version of this called a CDMA Subscriber Identity Module
(CSIM), which are cards developed for CDMA handsets that are
equivalent to a GSM SIM. The CSIM is physically compatible with GSM
SIMs, can fit into existing GSM phones, and is an extension of the
GSM standard but is capable of working on both CDMA and GSM
networks.
[0016] Removable identity modules can designate one or more pieces
of software to run when a device is powered on with the identity
modules. Removable identity modules thus provide a mechanism for
surreptitiously installed software to be installed and then moved
between devices.
[0017] From the foregoing, it will be appreciated that effective
covert monitoring of a mobile device requires the combination of
several technologies and techniques that hide, disguise, or
otherwise mask at least one aspect of the monitoring processes: the
covert identification of the mobile devices to be monitored, the
covert installation and control of the monitoring applications, and
the covert exfiltration of collected monitoring results. As used
herein, "covert exfiltration" refers to a process of moving
collected monitoring results from a mobile device while it is under
the control of another without their knowledge or awareness. Thus
covert exfiltration processes can be those using stealth, surprise,
covert, or clandestine means to relay monitoring data. "Collected
monitoring results" as used herein includes any or all materials
returned from a monitored mobile device to other devices, using
either mobile or fixed points-of-presence. Examples of collected
monitoring results include one or more of the following: command
results, call information and call details, including captured
voice, images, message traffic (e.g. text messaging, SMS, email),
and related items such as files, documents and materials stored on
the monitored mobile device. These materials may include pictures,
video clips, PIM information (e.g. calendar, task list, address and
telephone book), other application information such as browsing
history, and device status information (e.g. device presence, cell
towers/wireless transmitters/points-of-presence used, SIM data,
device settings, location, profiles, and other device information).
Additionally, the capability to covertly utilize a mobile device as
a covertly managed camera or microphone provides other unique
challenges.
[0018] Thus covert monitoring of a mobile device's operation poses
the significant technical challenges of hiding or masking the
installation and operation of the monitoring application, its
command and control sessions, hiding the collected monitoring
results until they are exfiltrated, surreptitiously transmitting
the results, and managing the billing for the related wireless
services. The exemplary illustrative technology herein addresses
these and other important needs.

covertly, transparently, and remotely distributing, installing,
instantiating and managing applications and data on mobile devices
with at least one network interface. As it is desirable to
implement a system that adapts to incorporate as many devices as
possible, the present invention provides a system with a common
interface that is independent of device type, device data
connection, device network, or device capabilities to the extent
possible.

control software installed on a mobile device to a defined location
or external system. Various embodiments of this aspect of the

[0038] More particularly, the present invention provides systems,
methods, apparatus, and software (such as encoded on a computer
readable medium as computer readable program code devices to cause
a computer to take instructed actions) for wirelessly
surreptitiously installing, monitoring, and operating software on a
mobile device. In some embodiments, the systems, methods,
apparatus, and software include or enact a control system for
communicating programming instructions and exchanging data with the
mobile device. Among those embodiments are embodiments in which the

and illustrative examples will now be described.
[0041] FIG. 1 illustrates an exemplary mobile device monitoring and
control architecture in accordance with one embodiment of the
present invention, in which a first monitored mobile device
communicates with a control system to provide device monitoring and
management features under the control of the control system. The
exemplary mobile device monitoring architecture comprises a control
system (1400), which further includes a control service (1410), a
module repository (1420), an exfiltration data service (1430), a
listen-only recording service (1440) and a WAP Gateway (1450), each
of which is connected through one or more wireless networks (e.g.
1200a) such as a cellular network or other wireless network such as
a WiFi (802.11b/g) wireless network (e.g. 1200b) to any of a
plurality of monitored mobile devices (e.g. 1100a, 1100b), through
a computer implemented device controller (1490) as described in
greater detail below. Implementation of these elements can be
accomplished by those having ordinary skill in the art.
[0042] Continuing with reference to FIG. 1, the Figure also
illustrates a wireless communication system architecture (1000) in
which a first monitored mobile device (1100a) communicates with a
computer implemented device controller (1490) in accordance with
one embodiment of the invention. A monitored mobile device (1100a,
1100b) is capable of connecting to wireless telephony networks and
associated wireless data networks, and can comprise devices such as
cell phones, PDAs, handheld or laptop computers with cellular
modems, and are described in more detail below and with reference
to FIG. 2. Each monitored mobile device (1100) communicates through
one or more wireless communications networks (e.g. 1200a, 1200b)
that each include a gateway (1210a, 1210b) that is in communication
with a computer network (1300). Some examples of wireless
communications networks (1200a and 1200b) include cellular
telephone networks utilizing CDMA (Code Division Multiple Access)
or GSM (Global System for Mobile communications) technologies, and
wireless metropolitan or area networks utilizing 802.11-based
technologies. The wireless communication networks enable the
wireless transmission and reception of information between mobile
devices and external systems. Wireless communications can provide,
in addition to voice telephony communications, data communications
capability, such as TCP/IP-based protocol support, or more limited
data communications means using SMS, MMS, FLEX, and other messaging
protocols. Additionally, wireless communications can involve
communications using peer to peer communications mechanisms, such
as Bluetooth, and can even provide hybrid communications using one
or more of the above communications means simultaneously or
sequentially. Exemplary wireless communications networks (1200a,
1002c, and 1200c) are composed of components having designs,
materials, and methods well known to those of ordinary skill in the
art.
[0043] The network (1300) provides communication with a device
controller that is in communication with one or more services or
servers, and at least a first monitored mobile device (1100).
[0044] The control system (1400) further comprises one or more
instances of services hosted on one or more computer systems,
commonly called services. Each service may be operated on a
computer, which is commonly called hosting. Each service is hosted
on a single computer or alternatively, instances of each service
can be hosted on several discrete computers. Further alternative
configurations can provide for several different services to be
hosted on a single computer.
[0045] The device controller (1490) of the control system (1400)
provides communications support and routing selection between each
particular monitored mobile device and server components such as a
control service (1410), a module repository (1420), an exfiltration
data service (1430), a listen-only recording service (1440) and a
WAP Gateway (1450). Components (1400, 1410, 1420, 1430, 1440, 1450
and 1490) can be integrated into a single component, or implemented
as one or more separate server devices and database components as
shown in FIG. 1. The device controller (1490) selects one or more
communications networks and methods for communicating between a
particular monitored mobile device and one or more service
components. The selection can be made upon a variety of factors and
may be made automatically or under control of a person operating
the device controller. Some factors that may be used by the device
controller in the selection process include the device ID, device
OS, device status, network availability, network device user
configuration, network carrier configuration, version and
capabilities of software on the monitored mobile device, and the
instructions of the control system operator. In a first exemplary
embodiment, the device controller (1490) can select an SMS
communication link using a commercial cellular telephone network,
such as those provided by commercial service providers like Verizon
or AT&T/Cingular. In a second exemplary embodiment, the device
controller (1490) can select a TCP/IP communications link using a
wide area wireless network such as metropolitan wireless network
such as those provided by Earthlink or MetroFi. In some exemplary
embodiments the device controller (1490) can select a plurality of
communication links and permit the selective router module (2320)
on the monitored device to choose between them as detailed
below.
[0046] The device controller (1490) provides networking
infrastructure that permits each service to communicate with one or
more monitored mobile devices (1100) using one or more
communications networks and protocols as described above. The
device controller (1490) can be integrated into each service, or
can be structured as one or more additional components. The device
controller (1490) can optionally switch between wireless networks,
communication protocols, and can split or assemble communications
from partial communications using disparate networks. For example,
a device controller (1490) can use SMS to communicate with a
monitored mobile device (1100) when its status is not known, and
switch to communications on an 802.11 WiFi link when a monitored
mobile device (1100) is known to be in range of an 802.11 wireless
network. Additionally, a device controller (1490) can break a
larger message into smaller parts, referred to as fragments, and
communicate these fragments over protocols that are not capable of
communicating the entire message in one piece. The device
controller (1490) also can receive message fragments from a
monitored mobile device and "reassemble" them into complete
messages for processing by a service.
[0047] Additionally, the device controller (1490) can be configured
to determine an appropriate way to reach a specific monitored
mobile device using a combination of state information and routing
information. Thus, as a monitored mobile device moves from being
only reachable on a cellular network, to being reachable on a
higher bandwidth 802.11 based wireless network, to being reachable
using a peered device as a proxy or gateway, to being completely
inaccessible, the device controller (1490) can consolidate this
information and provide a common means for most efficiently
reaching the monitored mobile device (1100).
[0048] The device controller (1490) also can provide message
encryption/decryption, determine device status based upon periodic
reporting (e.g. heartbeat), and other services as will be described
in further detail below.
[0049] Services (1410, 1420, 1430, 1440 and 1450) preferably
communicate with each monitored wireless mobile device (1100a,
1100b) using the device controller (1490) as described above.
Alternatively, the services can communicate directly with a
monitored wireless mobile device. Direct communication with a
monitored wireless mobile device means communicating with the
monitored mobile device (1100) using a well-known protocol such as
TCP/IP in the case of wireless networks (such as 802.11 networks)
using common networking protocols. In telephony based networks such
as CDMA or GSM networks, direct communications with a monitored
wireless mobile device means communicating with the telephony
network provider's network interface using a well known protocol,
and having the network interface communicate with the monitored
wireless mobile device on the service's behalf using a telephony
protocol. In the illustrated example, services include specific
applications in the form of an exfiltration Data Service (1430) a
Control Service (1410), a Module Repository Service (1420), a
Listen-Only Recording Service (1440) and a WAP Gateway, each of
which in turn pass data to, and receive data from, a monitored
mobile device with a monitoring component ("monitored mobile device
client," 1120a/b). The monitored mobile device client (1120a/b)
also can serve as a filter between network traffic and the
applications (1110a/b/c/d) running on the monitored mobile device
(1100).
[0050] Although FIG. 1 illustrates a mobile device for illustrative
purposes, the term "mobile device" will be defined herein to
include not only traditional mobile devices including pagers and
cellular telephones, but also terminal devices, emulated devices,
and server devices connected to at least one wireless network.
Aspects of the exemplary, illustrative technology are equally
applicable to all classes of devices that experience intermittent
connectivity, such a laptops and PDAs that are intermittently
connected to a company LAN. In addition, although FIG. 1 shows
communication between a service (e.g., a server contained within
the network (1300) or within the device controller (1490)) and a
particular monitored mobile device (e.g., 1100a) it will be
appreciated by those of ordinary skill in the art that an arbitrary
number of devices can communicate with each other in accordance
with the technology as described herein. Thus, the exemplary
illustrative technology herein includes communications among all
types of devices.
[0051] 6.2 Module Repository 1420
[0052] The module repository (1420) is, in some embodiments, a
server device hosting the module repository (1420) service. In such
embodiments, the module repository (1420) service stores and
manages monitored mobile device modules, selects modules for
deployments, provides installer packages and configurations for
specific monitored mobile devices (1100), and manages known
monitored mobile device type-module associations. The module
repository (1420) can be constructed using a network appliance or
server computer running one of the server operating systems well
known to those skilled in the art.
[0053] The module repository (1420) maintains a database of modules
(described below) and manages a list of associations between
specific types of monitored mobile devices (1100) and modules that
can be used on those monitored mobile devices (1100). Types of
monitored mobile devices can be further categorized by the
operating system used, the communication service provider used by
the device, or by other relevant factors as determined by those of
skill in the art. Operating systems and other relevant factors can
be further categorized, such as by version numbers or options
installed. The modules themselves can be taken from a database, a
directory, shared files, or other storage means known to those
skilled in the art. In some embodiments, groups of modules can be
grouped together by the module repository (1420). The database of
modules provides a mechanism for identifying modules that may be
associated with a particular monitored mobile device (1100),
network provider, or other attribute.
[0054] In one embodiment, the module repository (1420) maintains a
database of tags associated with each module stored in the system.
The database of tags identifies a specific monitored mobile device
or device type (1100), operating system, and control function
provided by a module. A selection of modules that include a set of
well-known tags can be selected from the database using well-known
query techniques. For example, a query can be constructed to search
for all modules with a minimum set of tags. One such example query
might be constructed for a "Blackberry 1710" monitored mobile
device (1100) and would be for all modules that have a
"Device=Blackberry 1710" tag. A more refined query might be for
modules that have a "Device=Blackberry 1710" tag and an "OS=4.1"
tag. The tag can take the form of a database entry, or can be
contained within a digital signature certificate provided with the
modules.
[0055] In other embodiments, a list of modules for each specific
monitored mobile device (1100) or monitored mobile device
configuration can be loaded into the module repository (1420). The
module repository (1420) can use this list of modules to associate
specific modules with a specific monitored mobile device (1100) of
a known type. The list may be stored in a database, flat file,
directory service, or other storage means (not shown).
[0056] The module repository (1420) uses information obtained from
a device discovery and modification module (2310) in conjunction
with the pre-defined association information, and desired control
information, to construct a list of modules to be deployed to a
monitored mobile device (1100), and to provide a distribution
package for module distribution. Alternatively, an operator can
assign a list of modules to be deployed to a monitored mobile
device. The module(s) can be packaged using an appropriate
packaging technology, for example, Microsoft cab and dll files for
Windows, SIS files for Symbian, jar files for J2ME, or other
packaging and distribution means appropriate for the destination
mobile device. The module repository (1420) can encrypt the package
using a common or device-specific key to protect the contents. In
some embodiments, one or more modules can be pre-associated and
delivered as a unit by the module repository (1420). FIG. 3 is a
process flowchart that details the steps performed by the module
repository (1420) to produce a package.
[0057] As can be seen in FIG. 3, in step 3110, the module
repository (1420) receives monitored mobile device information (for
example, one or more of device type, OS version, device ID, etc.)
from either the control service (1410) or directly from a monitored
mobile device (1100). In a first exemplary embodiment, the
monitored mobile device information is stored in a device database
and is made available to the module repository (1420) using that
database. In a second example embodiment, the monitored mobile
device information is provided directly to the module repository
(1420) as part of the service call. In an even more particular
embodiment, the monitored mobile device information is provided to
the module repository (1420) as parameters to a URI provided as
part of a service call to the module repository (1420).
[0058] In optional step 3120, the module repository (1420) receives
control information indicating the monitored mobile device (1100)
and the controls and modules to be deployed to the monitored mobile
device (1100). The control information may include such information
as the monitored mobile device (1100) ID and the desired controls
and modules for the monitored mobile device (1100). In some
exemplary embodiments, the control information is preconfigured
within the device repository or within a database accessed by the
module repository (1420). In other particular exemplary
embodiments, the control information is provided to the module
repository (1420) from another service, such as the control service
(1410).
[0059] In step 3130, the module repository (1420) uses the
monitored mobile device information and the control information to
determine the specific modules to use for the device discovery and
modification module (2310) and the control module (2340). Different
monitored mobile devices (1100) can have differing requirements for
the device discovery and modification module (2310) and control
module (2340) based upon device-specific characteristics, such as
monitored mobile device operating system (2100), configuration
parameters, and the like. Differing modules can be provided in
order to effectively manage and control modules installed to
different configurations of monitored mobile devices.
[0060] In step 3140, the module repository (1420) uses the
monitored mobile device information and the control information to
determine the monitoring modules to use for the monitored mobile
device (1100). Different monitored mobile devices have varying
hardware configurations, such as cameras and available memory, and
each piece of hardware can require differing modules. For example,
it makes no sense to deploy an image capture module to a monitored
mobile device (1100) that does not have an embedded image sensor
(e.g. a camera). Module deployment packages appropriate to each
known device type can be pre-built and stored for selection as
needed, modules can be stored individually and assembled into a
deployment package as needed, or a combination of these methods can
be used for different device types, as determined to be appropriate
by those having skill in the art.
[0061] In step 3150, the module repository (1420) selects or
constructs a deployment package for the device discovery and
modification module and control module(s) determined in step 3120.
The deployment package can be as simple as a list of modules to be
downloaded or a single file that contains multiple modules. The
single file may be a single module, or may be an installer package
as described above.
[0062] In some embodiments, the deployment package is protected for
integrity using techniques such as digital signatures that are well
known to those skilled in the art. Similarly, each deployment
package can be optionally encrypted using either public key or
symmetric key encryption. For example, a deployment package may be
encrypted using a key specific to a mobile device, such as the
mobile devices' device ID. Carrier and manufacturer device
identification numbers are good candidates for potential keys.
[0063] Once a deployment package is selected or constructed, the
module repository (1420) makes it available in a step 3160,
referred to as "publishing." Publishing the package makes the
package available to monitored mobile devices (1100) and other
services. In one particular embodiment, the deployment package is
published to a service that makes it available to the monitored
mobile device (1100) for download.
[0064] The process of selecting or constructing and publishing one
or more deployment packages for the modules to be deployed to a
monitored mobile device (1100) are repeated for the monitoring
modules. These steps are shown in the flowchart as steps 3170 and
3180.
[0065] In the flowchart of FIG. 3, steps 3150 to 3180 are shown as
discrete steps for clarity as to the functional aspects of the
process. Without loss of generality, in some exemplary embodiments,
steps 3150 and 3170 are combined for efficiency. Similarly, steps
3160 and 3180 may be combined for efficiency. Similarly, steps 3150
to 3170 may be repeated as often as necessary, and can produce
several deployment packages for a single monitored mobile device
(1100). Likewise, once a deployment package, or packages, has been
created for a particular device type, operating system or other
relevant factors, the package(s) can be stored, for example, in a
database, and used with a plurality of mobile device instances that
match the device type, operating system or other relevant factors
that the package was created for. This capability permits greater
efficiency, and shortens deployment time.
[0066] In step 3190, the module repository (1420) notifies the
device controller (1490) to initiate download of one or more
packages to a monitored mobile device (1100).
[0067] Modules downloaded to a monitored mobile device will
replace, modify, enhance, or otherwise alter the normal processing
of one or more aspects of the device operating system or other
typical software for purposes of implementing the technology
herein. Where the device operating system or other software
supports the concept of "loadable modules" (e.g. "dynamic loadable
libraries (DLLs)", "plug-ins", or "drivers"), it can be possible to
implement one or more of the downloaded modules in the form of
loadable modules and incorporated into the monitored mobile
device's systems using the facilities present in the device to
support this mode of operation. In some cases it can be possible to
replace the monitored mobile device's operating system in whole or
in part with software that supports the monitoring and other
aspects of the technology described herein in addition to providing
the expected behavior in the monitored device from the point of
view of the device's user, service provider, and other entities
that are not involved in the monitoring and other activities of the
technology described herein. In some cases the original device
software can be retained and used in whole or in part to accomplish
this, while not being allowed to regain full control over the
monitored device.
[0068] 6.3 Control Service (1410)
[0069] The control service (1410) provides command and control
services to the control system (1400). The control service (1410)
provides a database of devices currently being monitored, in which
information about each monitored mobile device (1100) is stored.
This information includes monitored mobile device identification
information, such as IMEI (International Mobile Equipment
Identity), IMSI (International Mobile Subscriber Identity), MIN
(Mobile Identification Number), and ESN (Electronic Serial Number),
along with assigned telephone number, monitored mobile device
configuration information, such as the version of the operating
system present on the monitored mobile device (1100), and monitored
mobile device information such as device type, model, and device
capabilities. For example, a device type and model can be used to
identify the specific equipment being used at the monitored mobile
device (1100). Device capabilities include the availability of GPS
or camera functions on the monitored mobile device (1100). The
database is also used to form associations between one or more
monitored mobile devices (1100), such as identifying monitored
mobile devices (1100) associated with one or more persons. The
database thus provides the ability to look up and control a
monitored mobile device (1100) if a user knows the identifying
information or a person associated with the monitored mobile device
(1100). Thus, the monitored mobile devices (1100) associated with a
particular person (e.g. a particular user's three cellular
telephones), or all of the cellular telephones belonging to a group
of people (e.g. the cellular telephones of a particular group of
interest), can be associated together. The ability to associate
disparate monitored mobile devices (1100) provides a mechanism to
provide common command and control to all of the monitored mobile
devices (1100) that are so associated together in a group.
[0070] The control service (1410) also manages the status of each
monitored mobile device (1100) known to it. The status of the each
monitored mobile device (1100) defines whether the mobile device is
currently online and available, the aspects of monitoring that the
device is configured to support, and whether the monitored mobile
device (1100) has uploaded all monitored information that has been
collected. Other information collected in the status of the
monitored mobile device (1100) includes whether a monitored mobile
device (1100) is reporting information on schedule, current state
of the mobile device and its security mechanisms (e.g. the device's
ability to perform the monitoring functions covertly), and whether
the mobile device is currently collecting monitoring (or not).
[0071] The control service (1410) is further able to issue commands
to and monitor requests from the control component of the
monitoring device client (1120). The control service (1410)
preferably operates in conjunction with the other services, in
particular, a device controller (1490), to send commands to and
receive responses from monitored mobile devices (1120). The control
service (1410) also monitors requests from monitored mobile devices
(1100), including data exfiltration requests and module download
requests. In some embodiments, the control service (1410) receives
these requests and forwards them to another service for processing.
In other embodiments, the control service (1410) receives
notifications of the requests from the service processing the
request.
[0072] The control service (1410) supports several commands related
to monitoring mobile devices. Examples of such commands are listed
in Table 1.
TABLE-US-00001 TABLE 1 Control Service Commands COMMAND FUNCTION
Collect Device Information Requests device information from the
network provider and/or monitored mobile device (1100). Obtains
device information, including operating system version, device
type, and device capabilities. Status update Requests a status
update from the network providers and/or one or more monitored
mobile device (1100). Install/uninstall module Requests one or more

[0073] The control service (1410) manages and controls operations
of other services of control system (1400). These services can be
used to extend the range of commands and functions provided by the
control service (1410).
[0074] The control service (1410) primarily communicates with other
services using a combination of service interface calls and
responses, direct application requests, and using various
event-based mechanisms. For example, the control service (1410) may
communicate with the exfiltration data service (1430) using a
service-based interface to determine a list of monitoring results
stored for a specific monitored mobile device (1100), and can
further communicate with a notification service (not shown) in
order to cause a specific user to be notified when new monitoring
results have been received for a specific monitored mobile device
(1100).
[0075] Lastly, the control service (1410) provides a user interface
for managing monitored mobile devices, commands, and the command
(results). In some embodiments, this is a web-based interface.
[0076] 6.4 Exfiltration Data Service (1430)
[0077] The exfiltration data service (1430) receives, stores, and
manages monitoring results exfiltrated from one or more monitored
mobile devices (1100). The information is stored by the
exfiltration data service (1430) as described below, and is
preferably cross-referenced by source device information. In some
embodiments, the exfiltration data service (1430) provides a file
store in which exfiltration data is stored. In alternate
embodiments, the monitoring results may be stored in a database or
other content management system that is part of the exfiltration
data service (1430). In some implementations, the exfiltration data
service (1430) provides key management service to manage the
encryption keys of encrypted monitoring results. Monitoring results
can be encrypted (or re-encrypted) by the exfiltration data service
(1430) in order to protect the monitoring results after they are
received from a monitored mobile device (1100). Similarly, the
exfiltration data service (1430) may digitally sign, or otherwise
protect for integrity, monitoring results using techniques
understood by those skilled in the arts. Protecting monitoring
results in this manner preserves their usefulness as evidence when
the system of the present invention is used by law enforcement
personnel.
[0078] The exfiltration data service (1430) makes this information
(monitoring results, key information) available to authorized
users. The information can be provided using a dedicated user
interface or as part of a service interface. In some embodiments,
the exfiltration data service (1430) can send a notification to one
or more services or users by sending an event, a service call, or
by other means when a specific monitoring result is received and
made available by the exfiltration data service (1430).
[0079] 6.5 Listen-Only Recording Service (1440)
[0080] The listen-only recording service (1440) provides a
telephone number, accepts a telephone call and a forwarding number
from the monitored mobile device (1100), and forwards the call to
the forwarding number, makes a recording, and sends the recording
to a data repository (not shown).
[0081] When the user of the monitored mobile device attempts to
place a call that requires monitoring, the monitored mobile device
temporarily blocks the call from being placed, contacts the
Listen-Only Recording Service (1440) to obtain a telephone number
and to provide the Listen-Only Recording Service (1440) with the
number the device user has attempted to call (the forwarding
number). The monitored mobile device then places a call from the
monitored mobile device to the number provided by the Listen-Only
Recording Service (1440). The Listen-Only Recording Service (1440)
places a call to the forwarding number, answers the call from the
monitored mobile device and, for the duration of the call from the
monitored mobile device, records the call and forwards the call to
the forwarding number. In this way the monitored mobile device user
obtains the expected call to the requested party, but the
Listen-Only Recording Service (1440) is enabled to record the call
for future use. In some exemplary implementations, the monitored
mobile device's call log is adjusted to show that the call was
placed to the originally requested number, rather than to the
number provided by the Listen-Only Recording Service (1440). In
some exemplary implementations the Listen-Only Recording Service
(1440) provides the monitored mobile device's identifying
information to the communication service provider when placing the
call to the forwarding number so that the call is reflected as
expected on the device user's account in order to maintain
covertness and surreptitiousness of operations.
[0082] An alternative method of operation for the Listen-Only
recording Service (1400) involves the monitored mobile device
placing the originally requested phone call to the originally
requested phone number, and including the Listen-Only Recording
Service (1440) phone number in a conference call arrangement, so
that the Listen-Only Recording Service (1440) is enabled covertly
and surreptitiously to record the telephone call. In some exemplary
embodiments, the monitored mobile device's call log is adjusted to
show that the call was not placed as a conference call, and the
call is placed in such a manner as to avoid conference call charges
appearing on the device user's account using methods described
herein. The methods used to place conference calls from wireless
mobile devices are well understood by those having skill in the
art.
[0083] When it is desired to record a call placed to a monitored
mobile device, the monitored mobile device transmits the data to
the exfiltration data service for storage, as with other gathered
data. When possible, such exfiltration is done as the call occurs.
Some devices, such as GSM phones, do not support concurrent voice
and data connections. On such devices incoming and outgoing (mobile
originated and mobile terminated calls) are recorded to device
memory as audio files while the call is active. When the call is
complete the recorded audio files are uploaded from the device's
memory to the server. When the files have been confirmed as
received by the server, the monitored mobile device deletes the
recorded audio files from the device's memory.
[0084] 6.6 WAP Gateway (1450)
[0085] The Wireless Application Protocol (WAP) Gateway (1450) acts
as a normal WAP Gateway service for the monitored device, but also
permits recording, blocking, filtering, delaying, redirecting or
modification of WAP requests from, and associated responses to, the
monitored device. The WAP Gateway service used by the device is
specified for the monitored device by the Device Discovery and
Modification Module, described below, as part of its normal
modification of the mobile device's configuration, policy and
provisioning settings. The WAP Gateway (1450) in some exemplary
embodiments performs all normal WAP gateway services for the
monitored mobile device. In other exemplary embodiments, the WAP
Gateway (1450) passes those WAP messages that are not blocked or
filtered, optionally after recording, delaying, or modification,
between the WAP gateway service originally configured for the
monitored mobile device and the monitored mobile device. Such use
of the originally configured WAP gateway service can simplify
implementation of the WAP Gateway (1450), and also provide an
approximation of expected traffic levels to and from the originally
configured WAP gateway service, which reduces detectable influences
resulting from the operation of the system of the present
invention, thus increasing its stealthiness in covert operation
scenarios.
[0086] The WAP Gateway (1450) can also be used as a method of
covert deployment for modules installed on a monitored mobile
device. By redirecting the monitored mobile device's WAP gateway
traffic through the WAP Gateway (1450), modules of the present
invention can be substituted for, or included with, software being
downloaded by the device or device user. This avoids a need for a
separate transmission of the modules, and "piggybacks" on a known,
expected or otherwise unremarkable network connection. In some
scenarios the user can install, or authorize installation of when
prompted, the modules, while believing they are desired software or
data.
[0087] In an alternate exemplary method of specifying the WAP
Gateway to be used by a device, a device that accepts WAP Gateway
settings in the form of signed WAP Binary XML (WBXML) sent via SMS
message can be reconfigured by creating a settings specification in
XML, converting it to WBXML and signing the result by methods well
understood by those having skill in the art. The signed WBXML is
sent to the device via an SMS message. The exemplary device, like
many in actual current use (such as those used by TMobile of
Olympia, Wash.), accepts signed settings without prompting the
device user. Once the settings are accepted by the device, the WAP
Gateway specified in the settings will be used, rather than the WAP
Gateway previously specified for use by the device. This method of
altering the WAP Gateway settings of the device is independent of
the existence of the Device Discovery and Modification Module on
the device, and can be used as a method of instantiating the Device
Discovery and Modification Module in some exemplary implementations
as described below.
[0088] 6.7 Network (1300) and Network Billing
[0089] The network (1300) provides communication with a control
system (1400) and one or more monitored mobile devices (1100).
[0090] A mobile device, such as a cell phone, is typically formed
of software, firmware, and hardware adapted to provide
communications services over a specific wireless network provided
by a specific network operator. This process of forming the
relationship between the mobile device and the wireless network is
known in the art as provisioning. Typically a network operator
provisions the mobile device in conjunction with a subscription to
a service contract. The service contract specifies the types of
voice and data services available to the mobile device user and the
charges associated with the use of those services. In some
instances, users form a temporary relationship with a service
provider using "prepaid" mechanisms that effect payment without a
formal service contract.
[0091] In a voice and data wireless network such as GSM (Global
System for Mobile Communication) and GPRS (General Packet Radio
System), CDMA (Code Division Multiple Access), or various other
third generation networks such as EDGE (Enhanced Data rates for GSM
Evolution) or UMTS (Universal Mobile Telecommunications Systems),
both voice and data services may be available to mobile devices.
Example voice services include voice calling and Short Messaging
Service (SMS). Example data services include Internet browsing,
email, and Multimedia Messaging Service (MMS).
[0092] Although many services may be available on a given network,
only those device users that use mobile communications devices that
have been provisioned for those services will be able to benefit
from them. This may present problems for the device user and the
network operator alike. Network operators provide "free of charge"
provisioning services to device users. These services are also
called "Type 0" services. Other services are provided by the
network operator for managing their network and device
configurations. Collectively, type 0 and related network
operator-provided management messages are called "carrier reserved
protocols".
[0093] Each monitored wireless mobile device (1100) communicates
through one or more wireless communications networks (e.g. 1200a,
1200b) each of which in turn is in communication with a computer
network (1300). Some examples of wireless communications networks
(1200a and 1200b) include cellular telephone networks utilizing
CDMA (Code Division Multiple Access) or GSM (Global System for
Mobile communications) technologies including wireless metropolitan
or area networks utilizing 802.11-based technologies. The wireless
communication networks enable the wireless transmission and
reception of information between monitored mobile devices and
external control systems. Wireless communications may provide
TCP/IP-based protocol support, can provide more limited
communications means using SMS, MMS, FLEX, and other messaging
protocols. Additionally, wireless communications can provide
communications using peered communications mechanisms such as
Bluetooth, and can even provide hybrid communications using one or
more of the above communications means. Exemplary wireless
communications networks (1200a, 1002c, and 1200c) are composed of
components having designs, materials, and methods well known to
those of ordinary skill in the art.
[0094] In some embodiments, the exemplary technology includes a
peer-to-peer network connection to a second device, which performs
as a proxy between the mobile device and the control system (1400).
The alternative technology provides for a proxy device, which can
be a mobile device as described herein, a server, or other computer
system such as a desktop computer. Alternatively, a network
appliance such as a cable modem or set top box may be used as the
proxy device. The proxy device provides for control channel and
exfiltration information to be communicated to and from the first
mobile device via the proxy device instead of communicating
directly with the first mobile device. Use of a proxy device is
effective for bypassing firewalls and monitoring systems using
peer-to-peer networks and protocols.
[0095] In one particular implementation, a peer-to-peer network
connection can be constructed between the first mobile device (the
monitored mobile device) and a second mobile device (e.g. the proxy
device) using a peer-to-peer network such as Bluetooth, Infrared,
or 802.11 technologies. Other wireless technologies can be used if
they are supported by both the monitored mobile devices (1100) and
the proxy device. Control information can be passed from the
control system directly to the monitored mobile device (1100), or
can be relayed through the proxy device. Exfiltrated information
can be passed directly to the control system, or can be passed to
the proxy device for forwarding to the control system. FIG. 4 shows
an exemplary peer-to-peer network connection where exfiltrated
information is passed from the monitored mobile device (1100c)
through a 802.11 connection (1200c) to proxy device (1500), which
then forwards the exfiltration information through PSTN/cellular
wireless network (1200d) to network (1300) to control system
(1400). Control information also can be passed in the opposite
direction through the network from control system (1400) to the
proxy device (1500) and then to the monitored mobile device
(1100a).
[0096] One challenge for covert operation over commercial networks
is masking or removing call detail records associated with
telephony and access services provided by wireless carriers.
Traditional service agreements provide for wireless device
customers to pay charges based upon their usage and to optionally
provide call details for all usage of the wireless device against a
specific account. Payment arrangements may vary, ranging from
monthly subscription, ala carte pricing, prepaid cards, and other
commercial schemes implemented by wireless network operators.
Various techniques can be used by the present invention to
circumvent the accounting and call details that are collected by
the wireless carriers.
[0097] In a first implementation, the present invention shifts
network traffic from a first wireless carrier's network to a second
wireless carrier's network. For example, the mobile device may be
instructed to route covert messages over a second wireless
operator's network where the charges for use of the second wireless
network are billed to the control system operator instead of the
mobile device user. This can be accomplished by providing
alternative device identification numbers that are registered with
the second wireless network, or by providing third party billing
information to the wireless network provider. Alternatively, the
network traffic can be routed to alternate networks, such as WiFi
networks if they are in range, where the WiFi network is either not
controlled or billed to the mobile device user, or for which
alternative billing options have been provided. An example of this
technique is to connect to a public WiFi network such as those
provided by Earthlink and to connect using an SSID and account that
charges the control system operator for use of the WiFi network.
Covert traffic may be sent using any of these techniques that
eliminate the charges and call detail record reporting to the
mobile device user for that covert traffic, having the effect of
hiding the traffic reporting on monthly statements.
[0098] In a second implementation, covert message traffic may be
charged as "type 0" traffic and thus be masked from the device
user's bill. In a variant of this tactic, the control system
operator may register as a content provider with the wireless
network operators, and arrange for usage of their "content service"
to be charged to them instead of the mobile device user.
[0099] Lastly, for users operating with prepaid services, the
control system can automatically replenish funds the mobile device
users' prepaid account to compensate the user for use. This
technique works because prepaid accounts generally do not provide
call detail information to the mobile device users but instead only
provide the remaining balance available.
[0100] 6.8 Monitored Mobile Device (1100)
[0101] A monitored mobile device (1100), as described above, can
include a cellular telephone, Blackberry, PDA, or other device that
communicates using wireless telephony and related data
technologies. These devices have a variety of capabilities,
including voice telephony, wireless data exchange, applications and
capabilities such as Personal Information Management (PIM), camera,
Global Positioning System (GPS), and other functions.
[0102] A Monitored Mobile Device (1100) is described in greater
detail in FIG. 2. A Monitored Mobile Device (1100) includes a
Device Operating System (2100) of standard construction known to
those having skill in the art, including, for example without
limitation, the Windows, Windows Mobile, or Windows CE operating
system available from Microsoft Corporation of Redmond, Wash.,
Unix, Linux, MacOS from Apple, Inc. of Cupertino, Calif., Symbian,
Nokia NOS, RIMOS, PalmOS, and NOS (Nokia Operating System). Still
other monitored mobile devices may not have an operating system per
se, but provide an environment for running Java 2 Micro Edition
(J2ME) programs, Binary Runtime Execution Environment (BREW)
programs, or similar execution programs and environments. In these
cases, the execution environment is considered to be acting as the
operating system. Typical monitored mobile devices (1100) include
cellular telephones such as those from Nokia of Helskini, Finland
and Motorola of Shamburg, Ill., and Blackberry devices from RIM of
Waterloo, Ontario, Canada.
[0103] A Device Interface (2200) provides a means for converting
data to signals compatible with network (1300). The device
interface (2200) may implement wired- or wireless communications
protocols. An example of one such wired communications protocol is
TCP/IP. Examples of a wireless communications protocol include WAP,
802.11x, and equivalent telephony protocols for wireless
telephones. The provision of a device interface (2200) to support
satellite telephony technology is also contemplated. The selection
and management of the device interface (2200) is made under the
control of Device Operating System (2100). Each device may be
constructed with one or more communications interfaces, which
enable the device to simultaneously communicate on multiple
networks.
[0104] Wireless monitored mobile device client (1120) creates,
manages, stores, and otherwise processes collected materials and
communicates with server applications (1410, 1420, 1430, 1440),
device controller (1490), and other service applications that can
be part of control system (1400). The wireless monitored mobile
device client (1120) manages and coordinates the operation of the
exemplary illustrative technology herein upon the monitored mobile
device (1100). The wireless monitored mobile device client (1120)
is often referred to herein simply as the "client". In simplest
form, the client (1120) receives messages from the control system
(1400) through the communications network (1200), device operating
system (2100), and at least one device interface (2200); manages
the instructions encoded in the messages, and sends responding
messages back to one or more services of control system (1400)
containing monitored mobile device information, user responses,
additional commands, and collected information (again through the
device operating system (2100) and the selected device interface
(2200)). In alternative embodiments, the client (1120) acts upon
the instructions encoded in the messages and downloads or causes to
be downloaded, one or more monitoring modules (collectively
modules) that provide additional features and functions to the
client (1120). Wireless monitored mobile device client (1120)
typically includes a device discovery and modification module
(2310), a selective router module (2320), a monitoring information
store module (2330), a mobile device control module (2340), and one
or more function-specific monitoring modules (2390a, 2390b). One or
more modules can be assembled together, and one or more modules can
be provided as part of a mobile device client (1120).
[0105] In one embodiment, the present invention communicates with
the client using the well known provisioning mechanisms through
which wireless devices interact with host systems. As will be
understood by those having ordinary skill in the art, most mobile
wireless devices include a capability to be "provisioned", or to
have their software updated, using one or more over-the-air (OTA)
methods by which certain messages are reserved for use by the
wireless carrier that can cause the device to load module and
configuration information without informing the devices user. In
some embodiments, the present invention uses such OTA protocols to
cause the wireless device to download (or to receive a download)
content (modules) to the device without device user notification
(i.e., a surreptitious download). The resulting message is accepted
by the device as authentic and causes the device to respond as if
the carrier had initiated a software load or configuration change.
For example, in some embodiments, such surreptitious communications
are performed by sending messages to a device that the device
accepts as a valid carrier messages. In more specific embodiments
such communications are accomplished by adjusting several of the
status bits in the message headers, by spoofing return addresses,
or by other suitable alterations to the message using methods known
to those of ordinary skill in the art.
[0106] In one more particular embodiment, the surreptitious
communication is accomplished by using SMS messages that are
interpreted by systems already installed on the device. In response
to properly constructed SMS messages, a target device is instructed
to accept software updates, accept changes to device configuration,
and many other actions. The present invention includes the use of
any suitable SMS message type, including such commonly used SMS
message types as WAP Push Service Load (SL) and WAP Push Service
Indication (SI) messages. As will be known to those of ordinary
skill in the art, SI messages are used to notify the device user
that new WAP content is available; SL messages cause the device's
browser to load the referenced content, optionally without user
intervention. In some embodiments, such SMS messages are designed
such that their loaded content includes the device discovery,
control modules, or both, of present invention.
[0107] 6.9 Modules
[0108] Modules enable a "pluggable" device monitoring framework
that provides system functionality in an extensible manner. Modules
facilitate the dynamic addition of new functionality to greatly
enhance the flexibility, robustness, and longevity of the system.
In one embodiment of the invention, each module is a compiled
binary that can be seamlessly OTA deployed into a monitored mobile
device (1100) running basic control (2340) and selective router
(2320) modules (e.g. the control framework) where the modules are
initialized and used by the system. Each specific module can be
initiated at any time during the monitored mobile device's life
cycle. A module also can be dynamically unloaded from the system
for replacement with newer versions or for complete deletion.
[0109] Physically a module is provided as a shared library (e.g. a
.dll (Dynamic Link Library) in Windows, or a .so or .sl in Linux.)
with a known or configurable entry point symbol in some
embodiments. In other embodiments, a module can be a standalone
executable or a Java application. The control module (2340) (or
other system component) takes care of loading the shared library
and initiating module. A single shared library can house multiple
application modules if desired, or it might only house a single
application module. In some embodiments, the control module (2340),
the selective router module (2320), and other functions can be
implemented as modules. In this way the entire monitored mobile
device management framework can be dynamically updated using the
built in mechanisms. Below is a list of the implemented modules for
framework and network connection functionality.
[0110] 6.9.1 Device Discovery and Modification Module (2310)
[0111] In some embodiments, the device discovery and modification
module are configured to discover the configuration and software
present on a specific mobile device, and to load the appropriate
selective router (2320) and control (2340) modules to that device.
In a first usage, the mobile device (1100) receives a message that
causes it to download and run the device discovery and modification
module (2310), which in turn performs the following process steps,
as depicted in FIG. 5. Often, in such embodiments the message
received is a provider service message (such as a type-0 message
for provisioning) that causes the mobile device (1100) to download
and run the device discovery and modification module (2310). This
message can take the form of a required network update message, a
provisioning message, or other message type recognized by the
mobile device. In devices that support software update or
installation through other communication paths, such as via TCP/IP
over WiFi, Bluetooth or other connection means, the device
discovery and modification module (2310) can be downloaded to the
mobile device using such means.
[0112] Alternatively, the device discovery and modification module
(2310) can be instantiated from an inserted SIM or memory card.
[0113] An alternative method for instantiating the device discovery
and modification module (2310) on the mobile device involves the
use of the WAP Gateway (1450) and WAP Gateway settings alteration
method described above. After redirecting a mobile device to use
the specified WAP Gateway (1450), any software download initiated
by the device user through the WAP gateway, such as a request for a
Java application, Active-X control, or other software device, can
be intercepted and replaced by or enhanced with a software device
that installs the device discovery and modification module. For
example, when the user, the browser or other application on the
mobile device requests download of a Java "jar" file (ajar file is
a transport format used to transmit Java programs and libraries),
the requested jar file is replaced by one that downloads and
installs the device discovery and modification module when run. The
device discovery and modification module downloads the originally
requested jar file so that the user, browser or other application
obtain the results intended in the original request, and then
continues with its other functionality as described herein.
[0114] Once instantiated, the device discovery and modification
module (2310) first identifies the device's operating system (OS)
and capabilities (that is, conducts device discovery for the
device) in step 5110. The device discovery and modification module
(2310) can make service calls to the device's operating system, or
can inspect one or more aspects of the device or its communications
interfaces, such as files stored on the device or the networks the
mobile device is within range of. For example, the device discovery
and modification module (2310) can determine the location of the
User Agent Profile document information and access that
information. In some embodiments, the device discovery and
modification module (2310) can cause the device to instantiate a
WAP or web browser interface to an external service. Alternatively,
the device discovery and modification module (2310) can query the
device's operating system to determine specific capabilities of the
device.
[0115] The device discovery functionality includes, in some
embodiments, mobile device capability gathering functionality. In
more specific embodiments, this capability gathering provides the
device type and capabilities (such as GPS and camera), mobile
device operating system information gathering, which yields the
device OS ID and version numbers, available memory information
gathering, available services gathering, and gathering other device
information as necessary. These results are packaged into a
response message that is returned to the control system (1400). In
some embodiments, the message is targeted to the control service
(1410). The message is processed by one or more services of the
control system to determine a specific list of modules that can be
readily deployed against the specific device. In some embodiments,
the device discovery and modification module (2310) then modifies
the mobile device's security policy, SMS and OTA provisioning
settings to allow the desired device access (step 5120). These
changes to the device configuration permit the further download and
instantiation of modules to the device. The specific changes are
implementation specific, however, the following general classes of
changes are made:
[0116] Security policy--the security policy or policies for the
mobile device (1100) are updated to permit module downloads and
invocation without user intervention. Specifically, the device
discovery and modification module (2310) then modifies the mobile
device's security policy to permit the device discovery and
modification module (2310), selective router module (2320), and
control module (2340) to operate. The device discovery and
modification module (2310) also can change or add to the list of
approved signing certificates to enable specific monitoring system
modules to be downloaded without user intervention. This involves
installing a signing certificate into the device and marking the
certificate as "trusted". Software signed using that certificate
will then be installable and executable. The exact method for
altering the list of approved signing certificates can vary with
the operating system type and version. For example, with a Windows
Mobile device, the following steps are performed to add a new
signing certificate to the trusted certificate store: [0117] 1.
Create a "_setup.xml" file containing an XML description of the
certificate details, including the trust store the certificate is
to be loaded into. [0118] 2. Create a ".cab" file that contains the
_setup.xml [0119] 3. Sign the .cab file with a public certificate
from a known/trusted Certificate Authority (e.g. GeoTrust,
Verisign, or Thawte). [0120] 4. Install the .cab file on the
device.
[0121] The XML description in the _setup.xml file has the following
general format:
TABLE-US-00002 <wap-provisioningdoc> <characteristic
type="CertificateStore"> <characteristic type="Privileged
Execution Trust Authorities"> <characteristic
type="[thumbprint, base64 encoded]"> <parm
name="EncodedCertificate" value="[certificate, base64
encoded]"/> <parm name="Role" value="255"/>
</characteristic> </characteristic>
</wap-provisioningdoc>
[0122] The methods used to create the XML description file and .cab
file, to sign the .cab file, and to install the file on the device
are well known to those with skill in the art.
[0123] Signing Certificates are obtained in various ways that
depend on the device, the operating system, and/or the device
manufacturer. In some cases, such as the Black Berry smart phone
from Research In Motion (RIM) of Waterloo, Ontario, Canada, a
signing certificate can be obtained by registering with RIM. When
the registration information is verified, a certificate is issued.
The Symbian OS, from Symbian Limited of London, United Kingdom, and
the iPhone from Apple, Inc. of Cupertino, Calif., use a similar
method. In some cases a separate Certificate Authority (CA), such
as Geotrust, owned by Verisign of Mountain View, Calif., can issue
certificates. In other cases, such as J2ME (used on devices from a
variety of manufacturers), the code of an application to be signed
is sent to the issuing authority, such as the device manufacturer,
as is the case with RIM's Black Berry smartphones, which tests the
code to ensure that it does what it claims to do, and then issues a
signing certificate for the application. In yet other cases, such
as Apple's iPhone, the device will only accept software downloads
from a particular server, though in some cases arrangements can be
made to specify a private server rather than that operated by the
device manufacturer. In these and other cases, use of a
"trojanized" application is necessary. In this method a signed
application is obtained, the certificate removed and additional
code added to the application, which is then re-signed as an
updated version of the same application.
[0124] SMS--the SMS configuration is modified to permit the receipt
and processing of SMS messages for the monitoring system without
user notification. The SMS system is further modified to hide
incoming SMS messages targeted to the monitoring system from the
user.
[0125] OTA--the OTA provisioning configuration is modified to
permit the receipt and processing of OTA downloads without user
notification. The OTA provisioning configuration can be further
modified to extend the list of "trusted" locations from which the
device can download modules OTA.
[0126] The device discovery and modification module (2310) then
loads any required digital certificates to the mobile device (step
5130). Most mobile device software is signed by the manufacturer,
and the software designed for the device must be digitally signed
using an approved signing certificate in order for the software to
load. In some embodiments, the modules to be downloaded into the
mobile device are signed using a commercially approved signing
certificate. In other embodiments, the modules are signed using a
different signing certificate. A mobile device typically stores
copies of the signing certificates required to validate module
digital signatures in its certificate store. The device discovery
and modification module (2310) checks the mobile device's
certificate store to ensure that all required digital certificates
are present in the certificate store, and adds any additionally
required certificates to the certificate store. Optionally, the
device discovery and modification module (2310) further checks the
device date and time to ensure that the device's date/time is
within the valid range of the installed certificates. This optional
step can permit new modules to be loaded without causing the device
operating system (2100) to generate an exception when new modules
are loaded. The digital certificates to be loaded into the
certificate store can be included within the device discovery and
modification module (2310), can be separate from the device
discovery and modification module, but packaged with it for
delivery to the device, or can be independently downloaded from the
control system (1400). In some embodiments, the download source is
the module repository (1420).
[0127] The device discovery and modification module (2310) then
accesses the device's data connection (step 5140). The device
discovery and modification module (2310) first identifies the
mobile device interfaces (2200) and the networks to which the
interfaces are connected, and attempts to determine available
network paths between the mobile device (1100) and the control
system. For example, the device discovery and modification module
(2310) identifies whether a mobile device's interfaces include an
802.11 interface, and if they do, determines if the 802.11
interface is enabled and within range of an 802.11 network. In some
embodiments, the device discovery and modification module (2310)
contains preferred 802.11 SSID's and authentication materials that
allow the device discovery and modification module (2310) to
establish an 802.11 network connection to well known 802.11
networks such as those provided by a commercial hot spot provider
such as Boingo.RTM., of Boingo Wireless, Inc. of Santa Monica,
Calif.
[0128] The device discovery and modification module (2310) then
selects and secures a method of communication with the control
system (1400) (step 5150). This step uses information collected
above in step 5140 as a starting list of available networks. The
device discovery and modification module (2310) attempts to connect
to one or more services of the control system (1400), using one or
more of the following protocols: SMS, IM, HTTP, FTP, WEP or email.
The results of these attempts indicate the preferable approach to
load and instantiate additional modules to the mobile device
(1100).
[0129] The device discovery and modification module (2310) then
loads (or causes to be loaded) the appropriate selective router
module (2320) and control module (2340) on the device (step 5160).
The device discovery and modification module (2310) then loads
other modules as appropriate for the mobile device. In some
embodiments, the device discovery and modification module (2310)
requests specific modules from the control system, in particular,
from a module repository (1420). In other embodiments, the device
discovery and modification module (2310) requests the modules
appropriate for a particular device from a control system service
and the control system service selects the modules to be downloaded
based upon the device discovery information (see above) and/or
operator specification. In a particular embodiment, the module
repository (1420) uses the device discovery information to
determine the modules to download, and makes these modules
available to the device discovery and modification module (2310)
for download. The device discovery and modification module (2310)
then downloads the modules and instantiates them on the mobile
device (1100).
[0130] The device discovery and modification module (2310) then
deletes itself and passes control to the control module (2340)
(step 5170), which ends the process. By implementing these
functionalities, the device discovery and modification module
(2310) allows successful loading of further monitoring and control
components of the present invention. The device discovery and
modification module's functionality is limited and specific; thus
the module has a small footprint, is stealthy, can remove itself,
and covers a wide range of devices.
[0131] 6.9.2 Selective Router Module (2320)
[0132] Referring back to FIG. 2, a selective router module (2320)
is responsible for monitoring one or more communications interfaces
(e.g. 2210, 2220, & 2230) of the monitored mobile device (1100)
and manages communications over the selected communication
interfaces. In some embodiments, the selective router module (2320)
additionally monitors specific message types, such as SMS. The
selective router module (2320), in a first aspect, functions as an
interface proxy service, in that the selective router module (2320)
inspects incoming and outgoing network traffic on each monitored
network interface and messaging method, and makes determinations as
to how to process this traffic. Typically the selective router
module (2320) intercepts and manages message communication via
multiple protocols such as WAP, HTTP, HTTPS, SMS/MMS, TCP, UDP and
USSD.
[0133] In some exemplary embodiments, the selective router module
(2320) is installed such that it retains the ability to monitor and
control specified incoming and outgoing network traffic even after
a monitored mobile device (1100) is rebooted. In some devices this
can require that the selective router module (2320) is loaded
before other software that is installed on the device, while in
other devices the selective router module (2320) can be loaded
after other software, but prior to any incoming or outgoing network
traffic being received or sent. Techniques for accomplishing this
requirement are well known to those with skill in the art. For
example a first method comprises replacing existing device
communication software modules with those of the selective router
module so that the selective router module is automatically loaded
during device startup and used by the device operating system or
other software to perform communication activities, and thus given
access to all device communication data. In a more specific
example, the Windows Mobile OS incorporates a mechanism, known as
the Radio Interface Layer (RIL) that handles communications between
the Windows Mobile system software and the device's radio hardware.
The RIL abstracts the details of the hardware components, which can
vary between a first device type and a second device type, and
provides a common known interface to the hardware for the operating
system and other software to use. The RIL, which is implemented as
a Dynamically Linked Library (DLL), can be replaced with a custom
DLL of an exemplary embodiment of the current invention. Provided
that the custom DLL implements the same software interface
functions as the RIL provides, the operating system and other
software will continue to function normally. The custom DLL
implements the RIL functionality in some exemplary embodiments,
while in other exemplary embodiments the custom DLL uses the
capabilities of the replaced RIL DLL rather than implementing them
itself. By taking over the RIL's position as the initial recipient
of requests for RIL functionality, the custom DLL is used by all
subsystems of the Windows Mobile device and is in a position to
intercept all incoming and outgoing Short Message Service (SMS)
data and can block, modify, filter, log, relay, or permit to pass
intact all such data.
[0134] In a second example method, the device hardware is
reconfigured to invoke aspects of the selective router module when
data arrives at the device's communication interface, and the
device operating system data structures are modified such that
requests to send data from the device result in the data being
passed to the selective router module, rather than the aspect of
the operating system that would normally perform the operations
necessary to send the data.
[0135] In a third example method, the device configuration is
modified so as to link the selective router module into the normal
device communication data flow using functionality present in the
device or device operating system. For example, in a Windows Mobile
device, the selective router module can be installed as a Windows
service, and will be loaded by the operating system each time the
device is booted. This is accomplished by installing required
registry keys: [0136] HKLM,Services\OEService,Dll,
0x00000000,name.dll [0137] HKLM,Services\OEService,Prefix,
0x00000000,OES [0138] HKLM,Services\OEService,Order, 0x00010001, 10
[0139] HKLM,Services\OEService,Keep, 0x00010001, 1 [0140]
HKLM,Services\OEService,Index, 0x00010001, 0
[0141] Selecting an innocuous name for the DLL file can reduce the
likelihood of suspicion about the service. For example, "IO.dll",
or "system.dll".
[0142] In a fourth example method, the selective router module
monitors message storage locations and acts on any messages that
are added to them. For example, the Symbian OS uses SMS storage
mailboxes for incoming text and service load or WAP push messages,
as well as outgoing text messages sent by client applications on
the device. By monitoring and acting on any messages that appear in
these mailboxes, SMS traffic can be filtered, blocked, monitored
and otherwise controlled.
[0143] When a device supports more than one method of intercepting,
controlling or blocking communication, such as replacement of a dll
and redirection of hardware pointers, a plurality of methods can be
used, with different methods used for each communication method
supported by the device, or a plurality of methods can be used at
once to deal with a given communication method. The preferred
method for a given device will be apparent to one skilled in the
art.
[0144] In any of these examples, the selective router module can
make use of the device modules that are replaced or superseded to
perform the actual data reception and/or transmission, once the
data has been logged, modified, or otherwise processed in
accordance with the design of the selective router module. This
permits the selective router module (2320) to filter, block, store,
modify or otherwise process network traffic prior to or instead of
the network traffic being processed by any other device software or
by any device hardware other than that required to deliver the
traffic to the selective router module (2320). On mobile devices
built using Microsoft Windows, the boot order is determined by
class IDs. Where the selective router module appears in the boot
order is based on the selective router module's class ID, when the
selective router module is implemented as a separate process. FIG.
6 depicts some different ways in which the selective router module
(2320) can interact with network traffic.
[0145] In addition to communication between a device and external
devices and systems, communication can also take place between a
SIM card and the device the SIM card is inserted into (referred to
herein as a "handset"). In some cases such communication is
initiated by messages sent from external devices and systems to the
SIM card, while in other cases the communication is initiated by
the SIM card or by applications running on the SIM card. To
maintain control over the device, the selective router module must
be able to block, modify, filter, log or permit such communication
between handset and SIM card. Methods similar to those used to
intercept and control external communication are applicable to the
handset/SIM card communication; including replacement of aspects of
the handset operating system, such as DLLs, and reconfiguring
hardware to interface with aspects of exemplary implementations of
the current invention rather than with the existing device
software. For example, The Symbian OS comprises a capability
referred to as the "Etelsat Layer", which deals with communication
between the system software and the device's radio hardware. Within
the Etelsat Layer, the RSat Interface provides handset software
access to SIM Toolkit procedures that exist on the SIM card. This
access is given to all applications, so there is no need to replace
the layer with a custom one. The SIM Toolkit procedures permit an
application to see Short Message Service (SMS) messages and
proactive communications between the handset and SIM.
[0146] The capability to selectively block or modify network
traffic entering or leaving the device can be used to protect the
selective router module (2320) and other modules and stored data
from interference by software updates that are performed using
network downloads. When such a download is detected, the download
can be analyzed by the selective router module in some exemplary
embodiments, and in other exemplary embodiments the download can be
redirected to the control service for analysis by automated systems
and/or human operators. If the download is determined to be
harmless to the selective router and other modules and data, it can
be permitted to be processed normally by the device. If the
download is determined to be of a nature that would remove,
disable, or otherwise interfere with the operation of the selective
router or other modules or data, such as an anti-virus system
update that includes detection capabilities for the selective
router or other modules or data, a patch to the operating system
that would remove the selective router by overwriting it with new
software, or a utility program that reports data that could
indicate the presence of the selective router module or other
modules or data, the download can be blocked, or be substituted
with an alternate download that does not remove, disable or
otherwise interfere with the operation of the selective router or
other modules or data.
[0147] Additional methods for avoiding disablement or removal of
the selective router module and other components and data used by
the invention, include removal of the selective router module and
other components from operating system "uninstall lists" (i.e.
lists of software that has been installed, which are used to prompt
the user for selections of software to be removed), and removal of
the selective router module or other components from displays of
running processes. In some devices, such as those running the
Symbian OS, there are features, such as the Symbian OS
"recognizer", that can be configured to restart the selective
router module or other components if they cease operating for any
reason.
[0148] In at least some devices it is not possible for the
selective router module to remain functional after a device is
reset to a factory initial state. Where the selective router module
can not intercept, block and simulate such a reset to convince the
user that it was performed when it was not actually performed, it
is necessary to reinstall the selective router module and other
modules and settings, for example, using one of the methods
described above.
[0149] In a first embodiment, the selective router module (2320)
notes the message traffic (6200) and uses the fact that there is a
particular type of network traffic to update the operations (6210)
of the selective router module (2320). For example, if the
selective router module (2320) notices that there is 802.11 (that
is, WiFi) network traffic, the selective router module (2320)
updates its internal tables to indicate that the system is
currently connected to an 802.11 network. This can be used to
trigger additional functionality of the module, as described
below.
[0150] In a second embodiment, the selective router module (2320)
captures copies of the network traffic (6300) and stores these
copies in the storage module ((2330), described below) for
subsequent exfiltration. The selective router module (2320) can
filter or otherwise limit the amount of network traffic captured.
The filtering can be performed based upon size, destination,
source, contents, or other attributes of the network traffic.
[0151] In a third embodiment, the selective router module (2320)
monitors and redirects network traffic targeted to specific modules
of the present invention. For example, a selective router (2320)
can monitor the SMS received queue (6110) and extract SMS messages
(6400) targeted for the control module (2340), and then deliver
these SMS messages directly to the control module (2340) without
further interaction being required by the monitored mobile device
operator. The selective router module (2320) also can delete any
user visible references to SMS messages targeted to the control
system and prevent these messages from being seen by any other user
or process. This includes deleting or hiding copies of the message
in system queues and notifications. This permits the modules to
receive network messages without interrupting the monitored mobile
device operator. In an alternative example, a TCP/IP intercept
(6500) can receive network traffic (6120) returned to an
application on the monitored mobile device (1100). However, the
TCP/IP traffic can have a covert payload destined from one of the
modules on the monitored mobile device (1100). The selective router
module (2320) removes the covert payload (6510) from the message,
forwards the message (6520) without the covert payload to the
intended destination (1110a), and forwards the covert payload
(6530) to the appropriate module (2390a) for processing.
[0152] In a fourth embodiment, the selective router module (2320)
intercepts network traffic sent from an application (1110b) on the
monitored mobile device (1100). In this example, the network
traffic is an HTTP request to a particular web server on the
network. After intercepting the network traffic (6600), the
selective router module (2320) rewrites the request (6620) to
forward the request to a service that is part of the control system
(1400), and optionally appends a covert payload (6610) to the
request. This technique is useful for covertly transmitting
monitoring information to the control system embedded within other
network traffic. In some embodiments the control system (1400) can
optionally embed commands or other data in responses to requests,
such as HTTP acknowledgement messages, or TCP/IP headers. Various
techniques for including the covert payload in the message traffic
can be used, including embedding encrypted payloads, adding
attachments to mail messages, steganographic methods for
information hiding, and other techniques well known to those
skilled in the art. In some embodiments, the covert payload can be
encrypted.
[0153] In a fifth embodiment, the selective router module (2320)
encrypts and decrypts network traffic sent between a monitored
mobile device and a control system (1400). In some embodiments,
commands sent by the control system to a mobile device are SMS
based, and are sent either to the default SMS port or to the
specific port identified during the post installation step.
Complete commands may span multiple SMS messages. In other
embodiments, other messaging mechanisms such as TCP/IP sockets, or
Bluetooth connections can be used.
[0154] In some embodiments, communications between the control
system (1400) and the monitored mobile device are encrypted, for
example by using a standard symmetric key encryption algorithm such
as AES, triple-DES, or other general purpose symmetric key
encryption algorithm supported by both the device and the control
system (1400). In one particular embodiment, the encryption key
selected is the device's IMEI number. If the key is less than 16
characters in length, the key will be padded with `$` to 16
characters. If the key is greater than 16 characters in length,
then the key is truncated to 16 characters.
[0155] Commands and modules downloaded from the control system
(1400) to the device are encrypted using the specified encryption
algorithm, the encrypted results are then optionally encoded using
a transport-encoding mechanism such as Base64, and then segmented
to fit within the selected network transport. After segmenting the
message, the unique device ID is prepended to the each message
segment to allow the messages to be appropriately managed by the
receiver Similarly, responses from the mobile device are also
optionally encrypted and encoded as described above. Exfiltrated
information is similarly encrypted and encoded as necessary.
[0156] The selective router module (2320) also is able to recognize
when specific network interfaces are enabled and connected to a
network and when monitoring information can be exfiltrated from the
monitored mobile device (1100) with a minimum chance of detection.
The selective router module (2320) can select the routing of the
exfiltrated messages (e.g. between an 802.11 network and a GPRS
network), and then package and route materials over the selected
network(s) using preconfigured defaults and access information. In
some embodiments, the selective router module (2320) uses
authentication materials that allow the selective router module
(2320) to establish an 802.11 network connection to a commercial
hot spot provider such as Boingo.RTM. by associating a well known
SSID with the authentication materials. In other embodiments, the
authentication materials can be downloaded to the monitored mobile
device (1100) after the available networks are identified. Without
limitation, the selective router module (2320) can utilize any
network interface available to the monitored mobile device (1100),
such as infrared, Bluetooth, or other point to point networks. When
operating in conjunction with a proxy device, the selective router
module can route specific types of network traffic to the proxy
device by routing messages to the proxy device over an alternate
peer-to-peer network interface, such as Bluetooth or peer-to-peer
WiFi, and the proxy device forwards the messages to the control
system.
[0157] Additionally, the selective router module (2320) can
identify network connections that are blocked by firewalls or do
not provide access to the control server and route traffic away
from these networks. In some embodiments, firewall identification
is performed by monitoring network traffic to and from the
monitored mobile device, for example, monitoring traffic to and
from a mobile browser application or to and from the network
provider. Alternatively, the selective router module (2320) can
probe the network to determine if a network path is open and
available. In some embodiments, the probe may take the form of a
Web request to a third party, such as a request to the Microsoft
Software update site. If the request is completed correctly, the
selective router module (2320) is able to use this information to
determine that the tested network path is probably not blocked by a
firewall. The above example illustrates the covert probing of a
network using requests that appear "normal" to an observer but
return useful information to the selective router module
(2320).
[0158] In some exemplary embodiments, the selective router module
(2320) is constructed or configured so as to use a particular
method or methods to route exfiltrating data from the monitored
device. Such particular method or methods can be the same for all
devices, preselected by device type, pre-selected based on specific
sets of characteristics of a particular device, or selected on a
device by device basis using automated systems that use a plurality
of factors, such as device type, device features, anticipated data
volumes, required level of stealthiness, available methods of
accepting exfiltrated data from monitored devices, or others.
[0159] In exemplary embodiments where the selective router module
(2320) is configured, rather than constructed, to use a particular
method or methods to route exfiltrating data from the monitored
device, the configuration data can be installed with the selective
router module (2320) or installed, or reinstalled, separately from
it. In exemplary embodiments where the configuration data is
installed separately, the selective router module (2320) is
typically designed with a default configuration to use in the
absence of such configuration data to prevent failure if the
configuration data is lost or is delivered after the selective
router module (2320) is activated.
[0160] In some other exemplary embodiments, the selective router
module (2320) is constructed and configured so as to choose a
method to use to route exfiltrating data based on factors such as
the capabilities of the device, the type of data to be exfiltrated
and the current device communication state. For example, if the
device has Wi-Fi capability, is located in a Wi-Fi hotspot, and is
currently transmitting and receiving data over Wi-Fi, the selective
router module (2320) can choose to exfiltrate data over Wi-Fi. At
another time the device might have the capability and connectivity
to send SMS messages, but not be located such that a Wi-Fi
connection is possible and the selective router module (2320) can
choose to exfiltrate data appropriate to sending over SMS, but
retain other data which is not appropriate for SMS exfiltration
until a Wi-Fi connection is possible. The selective router module
(2320) can optionally be designed or configured with parameters
that give preference to particular methods over other methods. As
will be apparent to those with skill in the art, such a weighted
selection procedure, whether based on the type of data or on other
factors, can be extended to any network path or Peer-To-Peer
connection that a device is capable of using, such as GPRS,
Bluetooth or IrDA.
[0161] In some exemplary embodiments, the selective router module
(2320) can detect and monitor the rate that data is being sent by
the monitored device due to user activity, and limit its own
exfiltration data rate in proportion to the monitored user activity
data rate so as to be less likely to attract the device user's
notice. In some exemplary embodiments, the selective router module
(2320) can notify the Device Controller (1490) or other appropriate
system component, of the monitored device's incoming data rate, so
that transmissions to the monitored device can be limited in
proportion as well.
[0162] As shown by the flowchart depicted in FIG. 7, in one
exemplary procedure for choosing a network path for exfiltration of
data, the selective router module (2320), first identifies
available network paths (7110). Such identification can be a
specific action or series of actions, such as querying the device's
operating system, reading device hardware state, or it can be done
incidental to the selective router module's other functions, such
as acting as a proxy for monitored device user activities. The
selective router module (2320) then identifies which of the
available network paths is currently in use, and calculates the
data rate for each (7120). The types and amount of data waiting for
exfiltration is then compared to the available network paths and
their data rates (7130) to select a network path for the waiting
data to be sent over. Criteria for matching data to network paths
and data rates can be designed into the selective router module
(2320), or they can be set by configuration parameters which are
read by the selective router module (2320). In general, matching
will select, or even require, higher bandwidth network paths for
data types such as sound or image data, that typically involve
large amounts of data, and select higher bandwidth network paths
over lower bandwidth network paths, to limit the duration of
transmissions and thus reduce the chance of the transmissions being
noticed. If there is no network data path that matches the waiting
data (7140), the process terminates, no network path is selected,
and the data continues to wait for exfiltration. If there is a
match found, the data that matches, which may be all or less than
all, of the data waiting for exfiltration, is sent using the
matching network path, at a rate that is proportional to the rate
that the network path was already sending data (7150). Once the
data has been sent, if there is more data to send (7160), the
process repeats starting with a re-check of available network paths
(7110), in case this has changed, otherwise the process
terminates.
[0163] The selective router module (2320) can include additional
factors in calculating when to exfiltrate data, which network path
to use, and what technique to use for exfiltrating data over the
selected network path. Such additional factors can include: [0164]
A send buffer becomes full. [0165] When cache space reaches a
specific level (e.g. 80% used). [0166] When there is any data at
all to send (i.e. send as soon as possible, don't cache). [0167]
When the device is sending other (non-exfiltration) data. (i.e.
when the exfiltration data can blend in with normal data traffic
flows). [0168] Send at least once in every specified interval of
time (e.g. send once an hour, once a day, etc.). [0169] Send at
specific times (i.e. 3 am, 7:20 pm, etc.). [0170] Send when located
in particular cell coverage areas. [0171] Prohibit send if located
in particular cell coverage areas.
[0172] Additional factors can be combined in some exemplary
implementations. For example, a selective router module (2320)
could be designed or configured to send data when cache becomes 50%
full, there is normal device traffic being sent, and the device is
located in particular cell coverage areas. A plurality of
conditions can also be defined. For example, a device can be
designed or configured to send when cache reaches 50% of capacity
and normal device traffic is being sent, but if cache reaches 80%
full, sending can occur even if there is no normal device traffic
being sent.
[0173] 6.9.3 Monitoring Information Store Module (2330)
[0174] The monitoring information store module (2330) provides a
hidden storage for collected monitoring information prior to
exfiltration. In some embodiments, the monitoring information store
module (2330) varies based upon the amount of information being
stored, whether the information must be hidden from the user of the
monitored mobile device (1100), and the type of device the
information is stored on. Table 2 lists the service operations
provided to other modules operating on the monitored mobile device
(1100) by the monitoring information store module (2330).

[0175] In more specific embodiments, the monitoring information
store module (2330) monitors the amount of stored information on
the monitored mobile device (1100) to prevent the device from being
completely filled by the collected monitoring information. If the
amount of storage used on the monitored mobile device (1100)
reaches a first threshold, the monitoring information store module
(2330) notifies the control module (2340) that the device is
becoming full, and that collected monitoring information should be
exfiltrated in order to prevent the data from becoming lost. If the
amount of storage available on the monitored mobile device (1100)
reaches a second threshold, the monitoring information store module
(2330) deletes some or all of one or more collected monitoring
information sets. Alternatively, the monitoring information store
module (2330) can compress one or more sets of collected monitoring
information. In still other embodiments, the monitoring information
store module (2330) can move one or more sets of collected
monitoring information to alternative storage (such as the SIM
card) if the alternate storage is available.
[0176] In some embodiments, the monitoring information store module
collects similar information together for ease of storage or
exfiltration. The collected information is called a database, even
through the internal data structure can be one of a database, a
e-mail box, a flat file, a compressed archive, or other storage
mechanism appropriate for the device and data type. Example of
types of information grouped together include: SMS messages in an
SMS database, e-mail messages in an e-mail database, call details
in a Call Detail Record database, and the like.
[0177] In some embodiments, the monitoring information store module
(2330) uses obfuscation techniques to hide the monitoring
information from users of the monitored mobile device (1100). These
obfuscation techniques are well understood to those skilled in the
art, and may include such techniques as: [0178] Hiding files in
directories [0179] Using hidden file names (for monitored mobile
device (1100) operating systems that support hidden file names)
[0180] False or misleading naming of files [0181] Naming files with
unprintable/unreadable names
[0182] The monitoring information store module (2330) also can
protect one or more pieces of monitored information using standard
encryption and/or digital signature techniques well known to those
skilled in the art.
[0183] 6.9.4 Control Module (2340)
[0184] In still other embodiments, the Control module (2340)
communicates with Control Services (e.g. Control Service (1410) of
the control system (1400)). In some embodiments, the control
service uses the services of a separate selective router to
communicate with a Control Service. In other embodiments, features
of the selective router are combined into the control module for
efficiency. The control module (2340) manages the deployment and
operation of the modules, including the update of existing modules
and the deployment and operation of monitoring modules. The control
module (2340) operates under the direction of one or more Control
Service(s). In a first embodiment, the control module (2340)
downloads and loads modules onto the monitored mobile device (1100)
as commanded, communicates status with control servers, tracks
device memory, deletes modules as commanded, detects debugging and
deletes files and components, and can self destruct if required.
After the control module is installed, communication with the
control system (1400) is made to receive the Device ID that
uniquely identifies the device the control module is installed on.
This request may be made in an SMS, HTTP GET or POST, or other
format. As will be understood by persons having ordinary skill in
the art, although each request parameter is not strictly required,
the more info that is provided, the better the control system
(1400) is able to uniquely identify the device. In more specific
embodiments, the control system (1400) stores the values provided
in its internal data store and generates a Device ID. The Device ID
will be used for identification purposes in all future
communication from the device to the control system (1400).
[0185] The control module (2340) monitors the status of the
device's SIM card, or SIM card equivalent to detect replacement of
the SIM card. This can be accomplished by means such as the device
making a "Refresh" request to the SIM card, to cause the SIM card
to notify the device of any changes in SIM files. An alternative
method for detecting a replacement of the SIM card in a device
involves use of an application on the SIM card that makes unusual
regular requests to the device that are not apparent to the device
user, such as setting up an "event list" or initiating a particular
Proactive SIM command. If these unusual regular requests are not
seen, the device uses this as an indication that the SIM has been
replaced by a new SIM. Those of skill in the art will know of yet
other methods of detecting SIM replacement in a device.
[0186] If a first SIM card is replaced by a second SIM card in a
first device, the control module on the first device obtains the ID
information from the second SIM card, and sends this to the control
system (1400), which updates the stored information for the first
device. In scenarios where the first SIM card was used to
instantiate the device discovery and modification module, insertion
of the first SIM card into a second device can result in the second
device instantiating a device discovery and modification module
that contacts the control system (1400). In such cases the control
system (1400) can instruct the second device's device discovery and
modification module to remove itself without installing any
additional components on the second device if monitoring of the
second device is not desired. Alternatively, the control system
(1400) can store the second device's information and begin
monitoring the second device too.
[0187] In a first usage, the control module (2340) receives an
incoming message from the control service (1400) or the selective
router (2320), parses arguments from the message and invokes
requested instruction, and reports status of instruction processing
to the control system (1400). The messages from the control service
or selective router have a specific header format as shown in Table
3.

[0188] Once decrypted, the text of the message contains header
information for the control module and application module specific
instructions. The message is in delimited ASCII encoding, using
"ctrl-k" and "|" as delimiters. The selection of delimiter
characters and encoding character set is implementation dependent.
In this example embodiment, the header information is separated by
"Ctrl+k" character. Each of the parameters are delimited by a pipe
(|). The elements within the delimited string are parameters that
define the meaning of the command. Additional parameters then may
be appended for commands sent to specific modules. The meaning of
these additional parameters is not necessarily known to control
module. It is expected that the module being commanded will
understand the parameters. The control module will always pass
these values through to the module without modification.
[0189] The Control module acknowledges receipt and provides
processing status for each command it receives. Additionally, the
device may periodically transmit messages to the control system
(1400) based on trigger events that may occur on the device (i.e.,
incoming SMS message, incoming phone call, device shutdown/startup,
etc.). An example format for these messages is illustrated in Table
4. All messages are sent to the control system (1400) using the
protocol and remote address identified via the Set Destination
process (see section 5.8.4.1.6). Response messages are formatted
and optionally encoded and/or encrypted as described elsewhere.

be used by the control module (2340) (or another module) to access
a control service (1400). This service address defines the protocol
and destination endpoint for processing responses from a mobile
device to a control service. The instruction processing status
callback address can be an SMS address, a USSD address, or a
service address defined by UDP, TCP, or URI address. Example
instruction processing status callback addresses include those
shown in Table 6.

[0192] 6.9.4.1 Control Module Commands
[0193] The following sections describe the control module
functioning in response to various commands.
[0194] 6.9.4.1.1 Install Module Command
[0195] The Install Module command allows the control system (1400)
to instruct the control module to load new modules onto the device
via the control module application. A message (header portions
truncated for clarity) specifying the control parameters below is
received by the control module and processed.

device, and assigned the "target application ID" provided in the
control message (see above).
[0197] An example of a textual version of an install command
received by a mobile device is shown below. The example uses
"ctrl-k" and "|" as delimiters, and is shown without encryption,
base64 encoding, or other adjustments. It provides an example of
how the parameters described for a specific command are encoded for
transmission over a textual transmission mechanism such as SMS.
Other encodings are possible within the scope of the invention and
may be performed by those skilled in the art.

[0214] The Set Destination command allows the control system (1400)
to configure the bearer, protocol and remote address the control
module application sends messages to. Each module installed on the
device (as well as the control module application itself) can have
its own destination configuration, and each destination
configuration can have a list of distinct remote destinations. Each
remote destination has associated with it a priority. The control
module application first attempts to send messages using the
highest priority destination available. In the event of a failure,
the control module application falls back to the next highest
priority, and continues until the send is successful or the list of
destinations is exhausted. Additionally, if a particular module
does not have a destination configuration defined, the control
module application uses its own destination configuration.

[0219] 6.9.5 Monitoring Modules
[0220] In some embodiments, the following feature specific modules
(e.g. 2390a, 2390b) are downloaded and run on a monitored mobile
device (1100). The functionality of each module described herein is
described as independent modules for clarity. However, as will be
appreciated by persons having ordinary skill in the art, the
functionalities may be combined into a subset of modules for
efficiency in deployment without loss of generality.
[0221] 6.9.5.1 Heartbeat Module
[0222] The heartbeat module provides presence and location data to
the control service (1410). The heartbeat function can be enabled
such that it reports back to the control service on a periodic
basis (for example, once every 10 minutes) and/or in response to
events on the monitored mobile device (1100) (for example, incoming
call, and power on/power off). This module runs without the user's
knowledge.

[0304] 6.9.5.7 Camera Module
[0305] The Camera module captures still images or video (with or
without audio) from the monitored mobile device's camera, if an
image or video capture capability was identified on the device. In
some embodiments, the camera module is configured to take one or
more images from the camera, on a command or timed basis as well as
when specified events occur, such as on device startup, when there
is an incoming phone call, when the device changes location, etc.
These images are exfiltrated to the control system (1440). The
methods of video capture are configurable and include the
following: [0306] Capture and store images [0307] Capture and store
video [0308] Events to capture images [0309] Events to capture
video [0310] Relay stored images or video, whether taken with the
camera or just stored on the device [0311] Relay during capture
(streaming) [0312] Image or video quality specification
[0313] The recorded images or video can be immediately streamed to
the control system (1400), or saved on the device for later
upload.

[0369] 6.10 Implementation
[0370] The invention can be implemented in digital electronic
circuitry, or in computer hardware, firmware, software, or in
combinations of them. Apparatus of the invention can be implemented
in a computer program product tangibly embodied in a
machine-readable storage device for execution by a programmable
processor; and method steps of the invention can be performed by a
programmable processor executing a program of instructions to
perform functions of the invention by operating on input data and
generating output. The invention can be implemented advantageously
in one or more computer programs that are executable on
programmable systems including at least one programmable processor
coupled to receive data and instructions from, and to transmit data
and instructions to, a data storage system, at least one input
device, and at least one output device. Each computer program can
be implemented in a high-level procedural or object-oriented
programming language, or in assembly or machine language if
desired; and in any case, the language can be a compiled or
interpreted language. Suitable processors include, by way of
example, both general and special purpose microprocessors.
Generally, a processor will receive instructions and data from a
read-only memory and/or a random access memory. Generally, a
computer will include one or more mass storage devices for storing
data files; such devices include magnetic disks, such as internal
hard disks and removable disks; magneto-optical disks; and optical
disks. Storage devices suitable for tangibly embodying computer
program instructions and data include all forms of non-volatile
memory, including by way of example semi conductor memory devices,
such as EPROM, EEPROM, and flash memory devices; magnetic disks
such as internal hard disks and removable disks; magneto-optical
disks; and CD-ROM disks. Any of the foregoing can be supplemented
by, or incorporated in, ASICs (application-specific integrated
circuits).
[0371] To provide for interaction with a user, the invention can be
implemented on a computer system having a display device such as a
monitor or LCD screen for displaying information to the user. The
user can provide input to the computer system through various input
devices such as a keyboard and a pointing device, such as a mouse,
a trackball, a microphone, a touch-sensitive display, a transducer
card reader, a magnetic or paper tape reader, a tablet, a stylus, a
voice or handwriting recognizer, or any other well-known input
device such as, of course, other computers. The computer system can
be programmed to provide a graphical user interface through which
computer programs interact with users.
[0372] Finally, the processor can be coupled to a computer or
telecommunications network, for example, an Internet network, or an
intranet network, using a network connection, through which the
processor can receive information from the network, or might output
information to the network in the course of performing the
above-described method steps. Such information, which is often
represented as a sequence of instructions to be executed using the
processor, can be received from and output to the network, for
example, in the form of a computer data signal embodied in a
carrier wave. The above-described devices and materials will be
familiar to those of skill in the computer hardware and software
arts.
[0373] It should be noted that the present invention employs
various computer-implemented operations involving data stored in
computer systems. These operations include, but are not limited to,
those requiring physical manipulation of physical quantities.
Usually, though not necessarily, these quantities take the form of
electrical or magnetic signals capable of being stored,
transferred, combined, compared, and otherwise manipulated. The
operations described herein that form part of the invention are
useful machine operations. The manipulations performed are often
referred to in terms, such as, producing, identifying, running,
determining, comparing, executing, downloading, or detecting. It is
sometimes convenient, principally for reasons of common usage, to
refer to these electrical or magnetic signals as bits, values,
elements, variables, characters, data, or the like. It should
remembered however, that all of these and similar terms are to be
associated with the appropriate physical quantities and are merely
convenient labels applied to these quantities.
[0374] The present invention also relates to devices, systems or
apparatus for performing the aforementioned operations. The system
can be specially constructed for the required purposes, or it can
be a general-purpose computer selectively activated or configured
by a computer program stored in the computer. The processes
presented above are not inherently related to any particular
computer or other computing apparatus. In particular, various
general-purpose computers can be used with programs written in
accordance with the teachings herein, or, alternatively, it can be
more convenient to construct a more specialized computer system to
perform the required operations.
[0375] A number of implementations of the invention have been
described. Nevertheless, it will be understood that various
modifications can be made without departing from the spirit and
scope of the invention. Accordingly, other embodiments are within
the scope of the following claims.
